1、下载EGORefreshTableHeaderView开源框架。

2、往应用中添加EGORefreshTableHeaderView.h文件、EGORefreshTableHeaderView.m文件、Resource目录，并且导入QuartzCore.framework

3、添加代码

 往tableview对应的类的头文件中添加如下代码 EGORefreshTableHeaderView *_refreshHeaderView;

BOOL _reloading;            - (void)reloadTableViewDataSource;      - (void)doneLoadingTableViewData;

 

 往viewDidLoad函数里添加如下代码

if (_refreshHeaderView == nil) {                            EGORefreshTableHeaderView *view = [[EGORefreshTableHeaderView alloc] initWithFrame:CGRectMake(0.0f, 0.0f - self.tableView.bounds.size.height, self.view.frame.size.width, self.tableView.bounds.size.height)];              view.delegate = self;              [self.tableView addSubview:view];              _refreshHeaderView = view;              [view release];                        }                    //  update the last update date          [_refreshHeaderView refreshLastUpdatedDate];

 

  再添加一些事件函数

#pragma mark -      #pragma mark Data Source Loading / Reloading Methods            - (void)reloadTableViewDataSource{                    //  should be calling your tableviews data source model to reload          //  put here just for demo          _reloading = YES;                }            - (void)doneLoadingTableViewData{                    //  model should call this when its done loading          _reloading = NO;          [_refreshHeaderView egoRefreshScrollViewDataSourceDidFinishedLoading:self.tableView];                }            #pragma mark -      #pragma mark UIScrollViewDelegate Methods            - (void)scrollViewDidScroll:(UIScrollView *)scrollView{                    [_refreshHeaderView egoRefreshScrollViewDidScroll:scrollView];                }            - (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate{                    [_refreshHeaderView egoRefreshScrollViewDidEndDragging:scrollView];                }            #pragma mark -      #pragma mark EGORefreshTableHeaderDelegate Methods            - (void)egoRefreshTableHeaderDidTriggerRefresh:(EGORefreshTableHeaderView*)view{                    [self reloadTableViewDataSource];          [self performSelector:@selector(doneLoadingTableViewData) withObject:nil afterDelay:3.0];                }            - (BOOL)egoRefreshTableHeaderDataSourceIsLoading:(EGORefreshTableHeaderView*)view{                    return _reloading; // should return if data source model is reloading                }            - (NSDate*)egoRefreshTableHeaderDataSourceLastUpdated:(EGORefreshTableHeaderView*)view{                    return [NSDate date]; // should return date data source was last changed                }

 

 最后，自己配置数据源进行测试。
